When I am acting, I have no control over how others will feel about my character.
How will they respond?
What’s happening in their life at that moment to influence the way they respond?
What nerves will I touch?
The only thing I CAN control is how I respond to the character. I can’t do anything other than have to pour myself into the role and give everything of myself that I can.
I can only then trust that I hit good nerves for the audience.
